RS485 Network Update
Posted by pbarrett on 2005-03-15 21:53:56 GMT
After many problems with the small PIC devices I am using (mainly limited program space) to develop this RS485 network, I have decided to reduce the network burden by using a very light weight protocol instead of full xAP.
The protocol I have devised is a fixed (10 bytes) packet protocol which runs on a 4800bps RS485 network. This protocol has the ability to implement the full BSC specification which is then converted into full xAP packets by the connector.
Once I have a prototype switch and output node I will upload the sources and documents to the website.
As the nodes will no longer be implementing the xAP protocol I will have to change the name of the devices. If anyone has any suggestions for the name please get in touch.

Paul
